In epistemology (theory of knowledge), a self-evident proposition is one that is known to be true by understanding its meaning without proof{{ safesubst:#invoke:Unsubst||date=__DATE__ |$B= {{#invoke:Category handler|main}}{{#invoke:Category handler|main}}[citation needed] }}.

Some epistemologists deny that any proposition can be self-evident. For most others, the belief that oneself is conscious is offered as an example of self-evidence. However, one's belief that someone else is conscious is not epistemically self-evident.

The following proposition is often said to be self-evident:

  • A finite whole is greater than, or equal to, any of its parts

A logical argument for a self-evident conclusion would demonstrate only an ignorance of the purpose of persuasively arguing for the conclusion based on one or more premises that differ from it (see ignoratio elenchi and begging the question).
